l ATTACHEEEN'I FOR CABBURETOR-S.

Application filed April 9,

T 0 all whom it may concern.

Be it known that I, VVinLL-iir H. LENZ, a citizen of the United States,residing at Lansing, in the county of Allamakee and State of Iowa, haveinvented certain new and useful Improvements in Attachments forGarlniretors, of which the following is a specification.

This invention relates to an attachment for carburetors of the floattype, and is designed primarily for use in connection with carburetorsof Ford cars, but it is to be understood that a carburetor attachment,in accordance with this invention, can be employed for any purposeswherein it is found applicable, and the invention has for its object toprovide, in a manner as hereinafter set forth, a carburetor attachmentincluding means for overcoming the stalling of a car when traveling upgrade on account of the gasoline supply being cut off due to the samebeing positioned at a lower level than the carburetor, and to this endthe invention consists in combining with the float chamber of thecarburetor an auxiliary reservoir rela tively to the float chamber thatthe reservoir will be supplied with gasoline to the same level as thelevel of the gasoline fed to the float chamber from the storage tank,and by this arrangement creating and holding what may be termed areserve body of gasoline at the carburetor to be used at such time as,when the car is traveling up hill and the flow of gasoline from thestorage tank to the carburetor is cut off by reason of the supply beingat a lower level than the carburetor, this reserve or extra supply ofgasoline at the carburetor will be sufiicient to enable the car totravel up grade and for adistance of one-half to a mile as by that timethe gasoline within the storage tank will be at a proper level so thatit can be fed to the carburetor.

Further objects of the invention are to provide a carburetor attachmentfor the purpose set forth, which is simple in its construction andarrangement, strong, durable, compact, thoroughly eflicient in its use;readily set up with respect to the carburetor, and comparativelyinexpensive to install.

With the foregoing and other objects in View, the invention consists ofthe novel construction, combination and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying 1923. Serial No. 630,934.

drawings, wherein is shown an embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views Figure 1 is an elevation of acarburetor showing the adaptation therewith of an attachment inaccordance with this invention, the attachment being shown in section.

Figure 2 is a sectional plan of the attachment. I

Referring to the drawings in detail, 1 denotes a carburetor of knownconstruction and which is connected in a knownmanner with the gasolinetank, so that gasoline can be fed to the carburetor when occasion sorequires. The carburetor 1 is of that type whereby the gasoline suppliedtherethrough to the intake manifold 2 'is controlled through the mediumof a float 3 and which is of known construction. The type of floatcontrolled carburetor, as indicated by the reference character 1,includes means depending therefrom to constitute a float chamber andwhich not only incloses the float 3 but also receives the gasolinesupplied from the storage tank and as is well known, the said float typeof carburetor, as indicated at 1, is formed with a i, from which dependsor to which is secured the means which provides the float chamber.

In employing a carburetor attachment, in accordance with this invention,no change is made whatsoever in the construction of the carburetor,other than with respect to the means which provides the float chamber,and there is substituted for said means a chambered receptacle dependingfrom the extension 4 and which provides the float chamber of thecarburetor and an auxiliary gasoline reservoir communicating with suchchamber. 1

The carburetor attachment, in accordance with this invention, comprisesa receptacle consisting of an annular body portion 5 of substantialdiameter, a concave bottom 6 formed integral with said body portion 5and a downwardly inclined top 10 extending inwardly from and formedintegral with the upper end of the body portion 5. Formed integral withthe upper face of the bottom 6, is a vertically disposed annularpartitlon depending extension till 7, of greater height than the heightof the body portion 5. whereby the said partition 7 will project abovesaid body portion. The partition 7, in connection with the bottom 6.provides a float chamber 8. The depending extension -1- extends into thepartition '7 and provides the top for the float chamber 8. The partition7 surrounds the extension 4, and is secured thereto in any suitablemanner. The partition 7 is spaced a substantial distance from the bodyportion 5. and forms in connection with the latter and the bottom 6 anauxiliary gasoline reservoir 9. which is closed at its upper end by thetop 10, and the latter is secured to the outer face of the partition 7at a point below the top edge thereof.

The partition 7 is formed with an opening 12 for establishingcommunication between the float chamber 8 and the reservoir 9. Thepartition 7, top 10 and extension 4 are bored to provide an air vent 13,for the escape of air from the reservoir 9 when the gasoline is suppliedto the latter, and the said air vent further provides for the entranceof air to the reservoir 9 when the. gasoline is being dischargedtherefrom.

The bottom 6 is provided with a central opening 11 for a purpose to bepresently referred to. i

As is well known, a carburetor of the float type. as indicated at 1. hasa depending hollow casing 17, formed with a reduced peripherally thraded extension 18 which projects through the opening 11 and is providedwith a securing nut 19. whereby the bottom 6 is coupled with thecarburetor 1. The bottom 6 of the body portion has a drain valve 16connected therewith.

The float 3 surrounds the upper portion of the extension and actuatcs anoperating element 20 for the gasoline inlet needle. not shown. when thegasoline, which is indicated at 20. is supplied to the float chamber 8.it will also be fed to the auxiliary reservoir 9 through the opening,port or passage 12. and the gasoline in the reservoir 9 will be at thesame level as the gasoline in the chan'iber 19. The accnn'uilation' ofthe gasoline in the reservoir 9 will provide for a reserve or an extrasupply of gasoline which will be held at the carburetor, and suchreserve or extra supply is to be used when the flow of gasoline from thestorage tank to the carburetor is cutoff by reason of the supply in thetanlt being at a lower level than the carburetor. and such reserve orextra supply of gasoline held at the carburetor will be sutticient toenable the car to travel up grade from one-half to one mile asby thattime the gasoline in the storage tank will be arranged at the properlevel so it will feed to the carl'mretor.

Making the bottom concave in cross section facilitates a discharge ofthe reserve bodyof gasoline from the reservoir 9 into the float chamber8 to enable the gasoline to be supplied to the engine The reservoir 9may be of a capacity for the purpose desired, or in other words. so

that it will hold or store preferably about a quart of gasoline which issuflicient to drive a Ford car up grade for a distance of from one-halfto one mile.

Although the preferred embodiment of a carburetor attachment inaccordance with this invention. is as described and illustrated. yet itis to be understood that changes in the details of construction can bemade which will tall within the light of the. invention as claimed.

hat I claim is '1. An attachment for carburetors of the float type,comprising a receptacle adapted to be connected with the carburetor bodyand consisting of an annular body portion, a concave bottom integraltherewith and a top integral with the upper part of the body portion andextendinginwardly therefrom. a vertically disposed annular partitionformed integral with said bottom and spaced from and extending abovesaid body portion and adapted to be connected at its upper end to andclosed by the carburetor body, said partition in connection with saidbottom :t'orming the float chamber of the carburetor and further formingin connection with said bottom and body portion an auxiliary reservoirsurrounding said chai'nber. and said partition having its lower portionprovided with means for establishing comn'iunication between thereservoir and the float chamber and further integral with said top.
